If anybody is interested in plotting some of data gathered in LeafSpy log files, I've made Octave script. The Octave is open-source program, similar to Matlab. It can be downloaded here:

https://www.gnu.org/software/octave/download.html

The script (*.m) files for reading LeafSpy logs can be get here:

Unpack all *.m files into the same directory. When starting Octave, select the "current directory" the same as the one where you put the *.m files.
Then type LeafSpy_UI in command window and press ENTER. The main GUI windows appears where you can choose your preferences.

After clicking "Load file and calculate", one of your Log files should be selected. The results are then plotted. Red vertical lines on the graphs (if they appear) represent time gaps in measurements.

See the pdf file for short explanation:

Other than the leafspy software, can someone give me a definitive list of the hardware required to run this app on an android device? Thanks in advance.
I have those two OBDs which both work with LeafSpy (you can find the same item also on amazon.com instead of amazon.de). However, note that I am using Android phones/tablets:

The second was ordered via AliExpress, but here is the same one if I am not mistaken:

LELink works via BlueTooth 4 connection, while the other one is communicating via it's own WiFi.
 
Hi
I have problem with loading *cvs files.

After 5 years of driving and more than 100000 miles, here are SOH charts for my Leaf 2.zero (40 kWh, MY 2018)

Average consumption was above 4.4 miles/kWh and daily SOC was between 40 % and 70 %. Current SOH is above 85 % (jumped up from 84 % few days ago).
